Although you may not think it, this plain grey wall is the largest legal graffiti surface in Germany, and has been for 10 years. Over the weekend, a number of graffiti artists will be respraying the wall in celebration. Not to be out-done, Strickbombe has contributed last summer's worse-for-wear but still colorful bike, with a little added extra. Maybe someone will save the bike by donating some replacement handlebars - someone obviously needed the original very urgently.
